lsaw pipe pile longitudinal double submerged arc weld pipe

Difference between ERW Pipes, SSAW Pipes and LSAW Pipes

Longitudinally Submerged Arc Welding (LSAW) pipes use single plate steel as raw material, applied double sided submerged arc welding. applied double sided submerged arc welding. The finished products have larger specifications and the welding joints have excellent ductility, plasticity and good sealing. (API), the LSAW pipe is the only
